Inconel 625 ERW Welded Pipe
Inconel 625 ERW Welded Pipe Property Information
Inconel 625 is a nickel-based high-temperature alloy renowned for its high strength, exceptional corrosion resistance, and good weldability, making its ERW (electric resistance welded) pipes suitable for the extreme conditions of industries such as chemical processing, marine, aerospace, and oil and gas. Key properties include excellent resistance to pitting, crevice corrosion, and chloride-ion stress corrosion cracking, as well as high fatigue strength and the ability to withstand a wide range of temperatures. The alloy's composition includes molybdenum and niobium, which impart its exceptional strength and corrosion resistance in a variety of harsh environments.
What are the properties of Inconel alloy 625?
Inconel alloy 625 offers properties that make it an ideal choice for seawater applications: low susceptibility to localized corrosion (pitting and crevice corrosion), high corrosion fatigue strength, high tensile strength, and resistance to chloride-ion stress corrosion cracking.
